NEW QUESTION # 70
Which statement best describes what happens when a 3rd-party backup tool is chosen to manage log backups for Microsoft SQL in NDB?
- A. Third-party backups vendors can continue to backup the binary logs from the binary log location. NDB will still be able to capture the logs, considering the log catch-up begins before the logs get purged.
- B. If exclusive log access is not granted to NDB, the Point-in-Time (PIT) recovery will not be supported, but snapshot-based recovery of the databases is supported.
- C. Third-party backups vendors can continue to backup the archived logs from the database log destination. NDB will still be able to capture the logs, considering the log catch-up begins before the logs get backed up
- D. If exclusive log access is not granted to NDB, the Point-in-Time (PIT) recovery will be supported, but snapshot-based recovery of the databases is not supported.
Answer: C

This is the first component in a Nutanix Environment Upgrade cycle2. The Era Cluster Agent is crucial for managing and monitoring the health of the Nutanix clusters1. Please refer to the official Nutanix documentation and training materials for more detailed information1.
NEW QUESTION # 74
Within the NDB GUI, an administrator needs to set the shortest schedule interval possible for a database log catch up.
Which value, in minutes, will satisfy this requirement?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: A
Explanation:
The NDB GUI allows an administrator to set the schedule interval for a database log catch up, which is the process of collecting transaction logs periodically from the source databases and storing them in the time machine. The shortest possible value for this interval is 15 minutes, as per the NDB documentation1. This means that the NDB time machine will capture the database logs every 15 minutes and use them for backup, restore, clone, and refresh operations.

NEW QUESTION # 75
Which statement best describes what happens when a 3rd-party backup tool is chosen to manage log backups for Microsoft SQL in NDB?
- A. Third-party backups vendors can continue to backup the binary logs from the binary log location. NDB will still be able to capture the logs, considering the log catch-up begins before the logs get purged.
- B. If exclusive log access is not granted to NDB, the Point-in-Time (PIT) recovery will not be supported, but snapshot-based recovery of the databases is supported.
- C. Third-party backups vendors can continue to backup the archived logs from the database log destination. NDB will still be able to capture the logs, considering the log catch-up begins before the logs get backed up
- D. If exclusive log access is not granted to NDB, the Point-in-Time (PIT) recovery will be supported, but snapshot-based recovery of the databases is not supported.
Answer: C
Explanation:
NDB supports two modes of log backup management for Microsoft SQL databases: NDB-managed and
3rd-party managed. In the NDB-managed mode, NDB takes full control of the log backups and stores them in the Cerebro log location. In the 3rd-party managed mode, NDB allows the use of external backup tools to backup the logs from the database log destination. However, NDB still needs to capture the logs for its own operations, such as point-in-time recovery, clone refresh, and log catch-up.
Therefore, NDB will periodically scan the database log destination and copy the logs to the Cerebro log location. This process requires that the log catch-up begins before the logs get backed up by the 3rd- party tool, otherwise NDB will miss some logs and the operations will fail. If the 3rd-party tool grants exclusive access to the logs, then NDB will not be able to capture them at all, and the operations will not be supported.

Answer: D
NEW QUESTION # 78
An administrator needs to protect a database with a Point In Time Recovery (PITR) SLA that provides a minimum of seven days of log recovery.
What is the minimum Default SLA that meets this requirement?
- A. DEFAULT_008 GOLD SLA
- B. DEFAULT_008 BRONZE SLA
- C. DEFAULT_008 SILVER SLA
- D. DEFAULT_008 BRASS SLA
Answer: C
Explanation:
Nutanix Era (NDB) utilizes DEFAULT_008 SLAs with varying frequencies for snapshots and log backups to achieve different recovery point objectives (RPOs). Here's how they compare: DEFAULT_008 GOLD SLA: Typically has frequent log backups (e.g., every 15 minutes) and snapshots every few hours. This is designed for critical databases with very low RPOs.
DEFAULT_008 SILVER SLA: Offers a balance between protection and resource usage. Log backups might occur every hour with snapshots less frequently. This SLA is often suitable for databases requiring a good RPO without being overly resource-intensive.
DEFAULT_008 BRONZE SLA: Has less frequent log backups (e.g., every few hours) and less frequent snapshots. This is used for databases with less stringent RPO requirements.
DEFAULT_008 BRASS SLA: This has infrequent log backups and is usually considered the least protective SLA with the longest potential RPO Reasoning:
Since the requirement is to have at least a 7-day log recovery period, any SLA with more frequent log backups than daily is excessive. The DEFAULT_008 SILVER SLA, with its hourly log backups, easily satisfies this requirement, offering the ability to restore to a point in time within the last hour of the past seven days.

NEW QUESTION # 79
An administrator would like to use Era for Copy Data Management operations on an Availability Group (AG) database.
The AG database is hosted on replicas with different named instances, as shown below:
* SQLAGNI\EMR
* SQLAGN2\EMR
* SQLAGN3\DW
SQLAGN3\DW is running the Analytics service that needs real-time data.
How should the administrator register the database in Era?
- A. Register the database as an Availability database.
- B. Register the database as a Standalone database,
- C. Register the SQLAGN3 from AG cluster and register the database as Availability database,
Answer: A
Explanation:
According to the Nutanix Database Automation (NCP-DB) learning documents, when dealing with an Availability Group (AG) database, the database should be registered as an Availability database1. This is because the AG database is hosted on replicas with different named instances, and registering it as an Availability database allows for Copy Data Management operations to be performed across all instances.
This is particularly important when services such as the Analytics service running on SQLAGN3\DW require real-time data1.
NEW QUESTION # 80
An administrator needs to perform patching on a MongoDB server cluster within an NDB environment.
How should the administrator accomplish this task?
- A. Apply the patch to all nodes at once.
- B. Perform a rolling upgrade, applying the patch to the primary member first, followed by the secondary members.
- C. Disable the replica set while patching.
- D. Perform a rolling upgrade, applying the patch to the secondary members first, followed by the primary member.
Answer: D
NEW QUESTION # 81
An administrator needs to take multiple snapshots per day and retain them for one week.
How should the administrator define and schedule the SLA?
- A. * Weekly snapshot retention: 1 week
* Snapshots per Day: 2 - B. * Daily snapshot retention: 7 days
* Snapshots per Day: 2 - C. * Weekly snapshot retention: 1 week
* Daily Snapshot at: 2 - D. * Daily snapshot retention: 7 days
* Daily snapshot at: 2
Answer: B
Explanation:
The correct answer is D because it matches the requirement of taking multiple snapshots per day and retaining them for one week. Option A is incorrect because it only takes one snapshot per day, which is not enough for the administrator's need. Option B is incorrect because it only retains the snapshots for one week, which means the older snapshots will be deleted after seven days. Option C is incorrect because it only takes two snapshots per week, which is not frequent enough for the administrator's need.
Reference: The following sources provide more information about the SLA retention policies and how to create and modify them in NDB:

This is part of Era's copy data management service, which includes components like Time Machine, one-click cloning and refresh, and one-click backup21.
NEW QUESTION # 83
Where should an administrator perform an upgrade within the Era management interface?
- A. Profiles Software
- B. Administration > Maintenance
- C. Operations > Current Recent
- D. Alerts
Answer: B
Explanation:
In the Nutanix Era management interface, an administrator should perform an upgrade under the Administration > Maintenance section1. As part of the upgrade process, the Era server is upgraded first, followed by all the Era cluster agents and database server agents in parallel1. The Dashboard displays the current version and an option to upgrade the Era server to a latest version when a new version is available for upgrade1. This ensures that the Nutanix Era environment is always up-to-date with the latest features and security updates1.
NEW QUESTION # 84
An administrator needs to perform LCM upgrades on an AHV cluster registered with NDB. The cluster hosts NDB-provisioned database server VMs that are part of a database server cluster.
What should the administrator do to allow the DB Server VMs to stay available while the cluster is being upgraded?
- A. Remove Nutanix Cluster
- B. Unset VM-Host Affinity
- C. Set VM-Host Affinity
- D. Update Nutanix Cluster
Answer: B
NEW QUESTION # 85
What is purpose of the NDB Database Agent service?
- A. Contains an instance of the database engine software.
- B. Schedules and monitors the NDB-related operations.
- C. Hosts one or more source databases for the same time machine.
- D. Temporarily stores the transaction logs.
Answer: B
Explanation:
The correct answer is C because the NDB Database Agent service is responsible for scheduling and monitoring the NDB-related operations, such as provisioning, patching, cloning, and restoring databases.
The NDB Database Agent service is deployed on the NDB server and on each of the database server VMs provisioned by NDB. It contains the tools required to perform each task and communicates with the NDB server through the NDB API. The other options are not correct because they describe different components or functions of the NDB solution. Option A is not correct because the transaction logs are not stored by the NDB Database Agent service, but by the NDB Time Machine service, which is a distributed file system that stores the database snapshots and logs. Option B is not correct because the source databases are not hosted by the NDB Database Agent service, but by the database server VMs, which are virtual machines that contain an instance of the database engine software and the database files. Option D is not correct because the NDB Database Agent service does not contain an instance of the database engine software, but only the tools required to perform the NDB-related operations. The database engine software is installed on the database server VMs, which are provisioned by NDB using the profiles defined by the administrator.

It's always a good idea to check the system's documentation or consult with the system administrator for the most accurate information.
NEW QUESTION # 89
An administrator needs to roll back an Oracle patch on a database server VM using NDB.
What is required for this action to be successful?
- A. The patch must have been applied using NDB.
- B. The patch must have been applied on Grid home only using NDB.
- C. The database must be in read-only mode.
- D. The database must be shut down.
Answer: A
Explanation:
To roll back an Oracle patch on a database server VM using NDB, the patch must have been applied using NDB in the first place. This is because NDB maintains a patch inventory and history for each database server VM and database that it manages. NDB uses this information to determine which patches can be rolled back and how to revert the changes made by the patch. If the patch was applied outside of NDB, NDB would not have the patch information and would not be able to roll back the patch.
Therefore, the patch must have been applied using NDB for the rollback action to be successful. The other options are not required for the rollback action. The database does not need to be shut down or in read-only mode, as NDB can perform the rollback operation online. The patch does not need to be applied on Grid home only, as NDB can roll back patches applied on both Grid home and Database home.

NEW QUESTION # 90
A customer has NDB configured to create snapshots of their production databases every 4 hours.
A developer requires a copy of the current production data at 7:00am of each day.
What is the most efficient way to meet this requirement?
- A. Configure a done with a daily Data Refresh Schedule at 7:00am.
- B. Configure Time Machine to create a clone from a daily snapshot at 7:00am.
- C. Authorize the developer in RBAC to create clones as required.
- D. Run a script which creates a clone from the latest snapshot at 7:00am.
Answer: B
Explanation:
Time Machine is a feature of Nutanix Era that allows you to create and manage snapshots of your databases. You can use Time Machine to create clones from any snapshot, either manually or automatically. You can also configure Time Machine to create clones from snapshots based on a schedule, such as daily, weekly, or monthly. This way, you can ensure that your clones are always up to date with the latest data from your production databases. In this scenario, the most efficient way to meet the developer's requirement is to configure Time Machine to create a clone from a daily snapshot at
7:00am. This will save the developer's time and effort, as well as reduce the storage consumption by using the existing snapshots.

NEW QUESTION # 91
An administrator is trying to register a database server VM with NDB.
Which file types will prevent the registration from being successful if located in the C:\ drive?
- A. System
- B. Database
- C. Page
- D. Backup
Answer: C
Explanation:
Page files are temporary files that Windows uses to store data that does not fit in the physical memory.
Page files can interfere with the registration of a database server VM with NDB, as they can cause errors or performance issues. Therefore, page files should be located in a separate drive or partition from the C:\ drive, where the NDB agent and other files are installed. System, database, and backup files do not prevent the registration of a database server VM with NDB, as long as they are not corrupted or incompatible with the NDB requirements.
